Ceramic membrane separation is a size‑exclusion process that relies on pore size, employing a dynamic cross‑flow filtration mode: the feed liquid is circulated at high velocity through the ceramic membrane pores by a recirculation pump. Under pressure, the clarified permeate passes through the ceramic membrane and the porous ceramic support, flowing outward perpendicular to the membrane surface, while the retentate is retained by the membrane and undergoes high‑velocity flow within the channels, generating turbulence that continuously flushes the inner surface of the membrane, removing any trace deposits adhering to the membrane and maintaining a steady effluent of clarified product. This process achieves fluid separation, concentration, and purification.
Filtration of biological fermentation broth
Fermentation broths used in pharmaceutical production have unique characteristics, primarily high mycelial concentration and high viscosity. Moreover, most fermentation products are thermally unstable; exposure to high temperatures, acidic or alkaline conditions, or specific solvents can lead to denaturation and loss of activity, thereby complicating downstream extraction and purification and compromising product quality. By contrast, ceramic membranes can efficiently remove large‑molecule contaminants such as mycelia, metabolic byproducts, and bacterial debris from the fermentation broth. They offer high separation precision, yield a clear and transparent permeate, and effectively prevent product denaturation and inactivation, enabling the production of a clarified filtrate that may even be sterile. With continuous backwashing, the residual cake retains only a very low solids content, theoretically allowing for higher extraction yields than those achieved with plate‑and‑frame filtration.
Treatment of Biopharmaceutical Wastewater
Biopharmaceutical wastewater is characterized by a high pollutant load, complex composition, and often exhibits antibacterial effects, making it difficult to treat using conventional biochemical methods. The ceramic membrane bioreactor represents an innovative technology that integrates biotechnology with membrane separation for wastewater treatment, offering a novel and highly efficient process. It boasts advantages such as superior effluent quality, a small footprint, high sludge concentrations, simple operation, and ease of automation, thereby providing a reliable new approach for wastewater treatment and water resource reuse in the biopharmaceutical industry.
In the pharmaceutical industry, ceramic membranes are typically employed in the production of high-value-added products. Consequently, pharmaceutical companies place stringent demands on the performance of ceramic membrane filters to minimize frequent shutdowns caused by high failure rates. This poses both a significant challenge and an opportunity for domestic ceramic membrane manufacturers.

Relying on a blood glucose meter, effectively test and distinguish blood sugar levels.
Using a blood glucose meter allows for effective, basic monitoring to determine whether blood sugar levels are within an acceptable range, making it a key tool for managing hyperglycemia and diabetes. For individuals already diagnosed with diabetes, regular, timed blood glucose testing—paying close attention to fluctuations in blood sugar—is of paramount importance. The “two hours after a meal” refers to the two-hour period counted from the moment food enters the body.
A blood glucose meter is an instrument used to measure blood sugar levels.
A blood glucose meter is an instrument used to measure blood sugar levels, primarily for monitoring the glycemic status of patients with diabetes. Regular use of a blood glucose meter allows individuals to closely track their blood sugar levels, enabling timely adjustments to diet and exercise to help manage the condition and prevent further progression. As such, it is an indispensable tool for people living with diabetes.
